<p>The invention provides a pair of pliers capable of properly pinching a screw head and reliably removing a screw from an object to which the screw has been fastened even if the screw has small thickness of a peripheral face to be pinched between pinching teeth. The pair of pliers is formed by coupling a first arm 1 and a second arm 2 each having a jaw portion 4 and a grip 5 through a coupling shaft 3 in an X shape. Each of the jaw portions 4, 4 is provided on left and right sides of a front end thereof with flanks 16, 16 for preventing opposite corners of front ends of each of the jaw portions 4, 4 from coming in contact with a screw fastened face 22. Each of the jaw portions 4, 4 also comprises longitudinal pinching teeth 13, 13 capable of pinching the peripheral face of the screw head 21 so as to be recessed in opposed faces of the respective jaw portions 4, 4 between the left and right flanks 16, 16. Each of the longitudinal pinching teeth 13, 13 is formed by connecting, in shapes of peaks and troughs, a plurality of streak teeth 13a in a front-back direction. Due to the flanks 16, 16, front ends 17 of the streak teeth 13a initially collide with the screw fastened face 22, so that the longitudinal pinching teeth 13 can reliably pinch the peripheral face of the screw head 21.</p> |
